Tips: Selection and use of reactor
Common reactors are line reactors, which are used to limit the current surge caused by sudden voltage changes and operating overvoltages in the power grid, and can smooth the spike pulses contained in the power supply voltage to improve the power quality. The single-phase DC reactor is mainly used between the DC link and the inverter link of the frequency conversion system. The main purpose is to limit the AC component superimposed on the DC current to a specified value. The main function of the three-phase output reactor is to compensate the influence of the long-distance distributed capacitance, and can suppress the output harmonic current, improve the output high-frequency impedance, and protect the inverter.
Common reactors, such as iron-core reactors, are characterized by small size, low leakage and loss, and can be used in high-voltage cabinets. However, the disadvantage is that the noise is large and the coil is burned out due to magnetic saturation. , Does not have a good ability to suppress harmonics and the ability to resist short-circuit current. The dry-type air-core reactor has strong overcurrent capability, and the mechanical structure is relatively simple and sturdy. It can also be used outdoors, but it has the defects of high active loss and electromagnetic interference to surrounding electrical equipment. In addition, there are types of reactors such as half-core reactors and magnetically shielded reactors. It can be seen that there are various types and functions of inverters. In actual power system applications, reactors with different functions should be selected according to needs.
